, This invention has for its ob ect to im-.

prove and simplify the construction of the various parts of acircular-knitting. machine adapted for circular and reciprocating knit?ting. In this class of machine as now made;

the thread-carrier when reciprocating knitting is bein. done fornarrowing and compleas in the production of tockings, has imparted to ita uniform throw, saidthi'ow being for a distance of more than one-halfof the circum-- n cntal 'wi( eiiing,

ference of the machine, andhence during recipro-cating knitting atake-up has to be. employed, said take-up being automatically orotherwise thrown into Working position'tov control'the slack threadbetween the end niost needles used in reciprocating knitting and thestoppingioint of the thread-carrier, and the length oi this slack threadwhich must be taken care of varies continually during reciprocatingknittin ()ne art of this invention -therefore,conipreheni is devices tostop the thread-guide during reciprocating knittin at or opposite thelast nee e fed by the thread-guide in its reciprocating stroke, andconsequently no slack thread 18 made, and therefore a take-up and itsactuatingmechanisin, always more or less complicated and delicate inoperation, become unnecessary.

In my invention the thread -guide is stopped close to the needle lastfed by it in circular knitting, and as said needle is the first one tobe fed for reciprqcatin knitting it will be readily understood that tunnecessary slack tread, and the thread is delivered constantly to theneedles throughout I substantially reciprocating knitting under the sameconditions and a erfectly made heel is insured, and so, also, ydispensing with the take-up yarns of less strength may be safely used inthe machine.

The machine which I have chosen herein to illustrate my invention is ofthat class wherein when the change from circular to reciprocatinknitting is to take place the points or switches of the knitting-camsare so changed be used therein are ere is no in their ositions astoactuate t e needles whic are not to be used in reciprocating knitting,the said cams engaging and depressing the first of the series of passunder and not needles to be used for the reciprocating coursethen to beknitted, the number of needles so depressed being more orless,accorde'ngth of the-course. Tlie-needles' ing to the of any reeiproeatincourse having been called into operation an having been moved to knitinthat course are then all returned into the massiof needles, and for thenext reciprocating course only the number of needles to depressed, andthey are a ain returned into pgsition with all the nee- (1 es. Machinesof t s general type are represented in an earlier patent, No; 453,059,granted to me on the 26th day of May, 1891, and also'in a patent, No,479,986," da'ted- August'2,1892, said latter patent being-anvimprovement on the former one.

he points or switches of the knittingcams occupy one position forcircular knitting, and when reclprocating knitting is to be done saidpoints are lowered wbetween two needles in the s ace at the junction ofthe non-knitting am the knittin groove, one of said needles being in theitting-groove immediately under the point, the lowered point being thusput into position to allow the next needle tothe one under its point,

and those following it while said point is depressed to ass over saidpoint and continue in the nonnittin groove, and by the time that thelast nee e to pass under the said point into the knittin -groove arrivesin the non-knitting groove the first needle to pass over said pointfollows it in line in the nonknitting groove. Putting all the needles inthe non-knitting groove during the last stroke for circular work leavesthe needles in position to commence reciprocating knitting for narrowingand widenin and to do this the actuating mechanism of t e cam-ringischanged so that its reci rocating motion commences, and in this f streciprocating stroke the points are raised at just the proper timebetween two needles, as stated, so as to enga e the butt of the firstneedleto be used for knitting in the reciprocating course said pointsremaining in such condition until it hastaken" from the non-knittinggroove enough needles, more or less, for that reciprocating course, saidneedles so taken from the non-knitting groove bein run through theknittinggroove, and t en the points are immediate I ferred to is forconvenience and adjustment of the position of the said stitch- 'from theneedle-su porting bed or cone.

novel means by which to automatically con- 2 sas es again loweredbetween two needles, as stated, ing reciprocating and circular knitting;but which prevents the taking of any more neeits pawls are so controlledthat they may he dles than those actuall needed from the nonput into andout of operative position. The knitting groove, and t is motion of thecamawl-carrier is actuated from a cam carried ring is continued untilall the needles put into liy a slow-moving shaft, (the shaft whichconthe knitting-groove have arrived again in the trols) thereciprocating motions of the manon-knitting roove. This operation isrechine,) the machine when circular knitting is peated for eachreciprocating course until the being done being run at a higher speed,as narrowing and widening has been e'llected. commonly practiced inmachines of this type. To automatically move these points or t Thetlu'ead-carrier is also a latch-guard, switches, I employ a toe-camhaving an osciland its hollow central hub is embraced lriclatingmovementabouta fulcrum'orpin and a tionall by a ring located centrally over thevertical movement on said pin toward and conical bedin which the needlesare reclpro cated. This hub may be and is herein shown as so supportedthat it may he turned The pin on which t to toe-cam turns forms part ofwhat may be designated as the-camup away from t 1e frame of the machineand ring of the machine, said toe-cam when in from above the latches ofthe needles to enits lowered position nearest the needle-bed l able theuse of a transferrer and the applicabeing adapted to meet and be turnedin one tion of work to the needles, or'it may be and then 111 anopposite direction by suitable turned down into working position, so asto lugs carried by rings which have only a tocover and protect the hooksand latches oi and-fro movement intermittingly. in a circutheoperating-needles. This huh has a suitlar path, said toe-cam having aslotted arm able arm or arms which may be struck by a which directlyengages a stud connected to ta'ppet or rojection moving with the camandextended upwardly from a plate fitted to rin and t )iS latter tap et isunder the conslide transversely in a guideway formed in tro of asuitable eamw ereby its acting end the outside of the cam-ring.

Fig. 4 is adetail chiefly to show thedevices for putting into and out of operative position the toe-cam andalso to start the lever employed to move the thread-carrier with thecam-ring, so that said lever will be put under the control of theautomatic devices l or moving it during reciprocating knitting.

Fig. 8 isan enlarged sectional detail of the toe-cam and some of its operatingdevices. Fig. 9 shows in perspective the toe-cam. Fig. 10 is a detailshowing part of the lever which cooperates with the thread-carrier tomove it continuously or intermittingly, as may be required. Figs. 1] and12 are details showing parts of the circularly-moving rings and theircams, to be described. Fig. 13 is a detail in side elevation of some ofthe devices employed for effecting the change from circular toreciprocating knitting, and vice versa. Fig. 14 shows the trol theworking position of the stitch-cam, and consequently the length of thestitch, the

cam being useful in fashioning the goods.

I have also sim liiied the means employed. to both rotate antreciprocate the cam-ring,l having reduced. the size and number of partscommonly used for that pur ose, and conseuently have reduced the weightof the parts, llhereby cheapening the construction of the machine andlessening the operative space re uired for it.

have also devised a novel means for imparting circular movement to themeans instrumental in determining when the points are to be changed inposition, said means includin rings having lugs and lyin one above the,ot er and presenting perip eral teeth which are engaged, respectively,each by one of a pair of pinions, one of the pinions of the pairimparting) movement to the other pinion of the pair, 0th pinionsconsequently eing actuatedby one pair of pawls directly under thecontrol of a suitable pattern-surface, the pawLcarrier beingin thisinstance of my invention movedcontinuously both dursection of the hollowcylinder or thread-carrier, showing the thread-guiding device and theopening in the bod of the cylinder for the passage of the thread to theoutside of the cylinder.

The framework of the machine consists essentially, of legs A, standardsA erected thereon, said standards having fixed to their upper ends abed-plate A, the, shape of which is shown best in Fig. 5, said platebcingpro vided with a central opening A, through which the knitted workpasses, said plate having secured thereto the shank B conical -needlebedA providedwith suitable grooves for the reception of a series of latchedend of said conical bedf needles a, theupper having a suitable pivot-orrest for a series of acks or sinkers A moved by a sinker-actuaprojeoting'ear' e en circular knittingis being done is acted uponcontinuously by one of two like studs a, carried by a plate a, to bedescribed, said late having two such studs to act alternatei on said earto move the ring A back and orth for reciprocating knitting. The shank Bof said conical bed is surrounded loosely by a cam-carrying rin B, saidring having teeth B to be engaged and moved by the teeth of thebevel-gear B. This ring B has attached to it by suitable screws a (seeFig. 1) the cam-lock a said cam-lock being shown detached in Figs. 6 and7. Said ring also at a point opposite said camlock has attached to it byscrews a the plate a before referred to, the weight of the plate a beingsuch as to form a balance for the weight of the cam-lock a". The ring B,it will beseen, thus becomes a cam-carrying ring, because it carries thecam-lock a, to be described. The bevel-gear B is adapted, as will bedescribed, to berotated at times forrotating the cam-ring duringcircular knitting and at other times to reciprocate it for reciprocatingknitting. The cam-ring B has attached to it by screws a 'flat feet a" ofa narrow ring a, the upper edge of which forms a continuation of theunder line of a non-knitting groove. The cam-ring so'made is a skeletonring, and its weight is so greatly reduced that its motion may bereversed without straining the machine to overcome its momentum, and thelighter the weight of the cam-ring the less the expenditure of power todrive it.

The shaft h, carrying the gear B, has fast ating rin A 'havin (see Fig.3,) which wii all times by a pinion A, fast on 'tached in Fig. .end'aroller'22 ofain a notch 16 of a p on it a pinion B, which is at alltimes ongaged b the teeth of a gear A loosely mounte on a main orslow-motion shaft A said shaft having fast on it. a toothed gear Apositively at the power or which is engaged and rotated driviizlg shaftA provi ed with any'usual devices by which to rotate it at a fast speedfor circular knitting- .and at a slower speed for reciprocating knit-'ting,- as common c ine.

The goal A has at one side a lime, (see Figs. 3 and 13,) which is cutaway at dia-' metrically oppositepoints, as shown in Fig. 13', for theopposite en y done in this class of inasofa sliding plate h, (shown de-14,) said plate having at one roller-stud 21', suitable springs 7vacting normally to cause said roller 22 to its periphery outside saidrim, suitable guides 23 acting against the side edges of the plate todirect its movement, said s rings also tending to normall keep theroler-stnd 21 ate A, fast on the slowmo'tionshaftA.

said shaft in practice being and. at its otherend a small stand with Thehub b of the disk a has loosely mounted on it a slpider A having aprojecting slettodarm "and carrying 'a ivoted dog it, acted upon by aspring h. has at itsfree end a lug which normally stands'in a notch 24inthe spider, said notch being enlarged at 25 next the end of said lug.

The framework of the machine has a vertical stud I)", (see Figs. 3 and13,) on which is pivotally mounted a .lever 6 upon one end of whichispivoted at b a shoe 1)", having a concaved face, said face standingnormally during circular knitting at one side of the rib a so that theroll as said gear is rotated does not strike the shoe.

When the plate is under the control of its springs and the shoe is notin the )ath of movement of the roll 22, then the roller-stud 21 standsin the notch 16 of the disk A locks said gear'A to said shaft A", andthe gear A is rotated continuously through said disk for circularknitting; but when reciprocating knitting is to be done the said shoe isturned automaticallyinto position so that the roll 22 may strike saidshoe, and the sliding plate is moved in a direction to cause theroller-stud 21 to leave the notch of the disk A, fast on said rotatingshaft, thus detaching the gear A from the disk and leaving the gear freeto be moved by some other source, said roller-stud 21 moving with thegear A, entering the notch 25 at the end of the dog it in the spider Aand as said spider is always reciprocating, as will be described, saidspider at once, by engaging said stud, be-

comes the moving device for said gear A and this gear will bereciprocated, and the cam-cylinder will also be reciprocated for rehedog and 80 assagethrough said rim ofzthe I i The slotted arm A of thespider has connected with it a link A, adjustably attached to a slottedarm A, fast on a rook-shaft A, said rock-shaft having an attached secondarm A, to which is adjustably attached a link A, (see Fig. 3,) in turnfitted at one end over a stud A, carried by a disk A", also fast on saidcontinuously-rotating slow-motion shaft A.

The shoe b is supported at one end by a suitable spring l).

The lever I) is (see Fig. 3) slotted at one end, and said slot receivesa pin (2, extended I from a lever d, pivoted at d on a lug of thestandard A. The lever 11 (see Fi 3) has connected to it at one end anelbowlever (1, (shown in section in Fig. 3,) the up or end of said lever(see Fi 2) being acte u on to move itat desired times by a suitab eprojection of the pattern-chain C, which is carried by a cylinder C,fast on a shaft e", which has secured thereto at one end a toothed wheelThe wheel 0 is actuated intermittently or step'by step to thus turn thecylinder 0 and move the pattern-chain by means of a cam-arm 0 extendedlaterally from the plate C, secured to the gear A, before described. Asthe gear A rotates the camarm C engages the teeth of Wheel C and turnsit, as will be obvious, and such movement will be intermittent,depending upon the character of arm C and number of revolutions of gearA The opposite end of said lever d isshaped to enter'a hole d? (see Fig.

lower end of a lever d, pivoted at d on a stand (1, depending from thebed-plate A, the upper end of the lever d entering a slot in an ear 11of a carriage d", fitted to slide in ways of a block d, fast on saidbed-plate, said carriage havinga cam-slot d, in which is entered a pind, extended from a slide-bar d fitted in a guide (1 upper end with twocontrolling-cams said cams occupyin their uppermost 081- tion (see Figs.2 and 4) when circular nittin is being done and being moved into theirlowermost position when reciprocating knitting is being done. i

The bedlate A has supported thereon a suitable hu e, which receives aposts, made and provided at it dis d),

. adjustable in said hub by a suitable set-screw e, to thereby adapt themachine to the size of cone used. This post has pivoted upon it at e asocketed arm e, in which is entered and held adjustably by a set-screw ean arm a having at its outer end a split collar 6, which may be clampedto ether by a suitable screw 6, said split col ar entering an annulargroove at the outside of the thread-carrier,

screw the collar may i) in an ad ustable link d, ointed at d to the andshown as com osed of a hollow cylinder e having at its ower end aflaring shielde, which serves as a thread-rest and a latchuard. Thecylinder has located centrally in it a thread-guiding device e, shown asa roller, to not only lessen friction, but also to facilitate the easyintroduction of the thread. The body of this cylinder below the splitcollar is provided with a suitable opening 0 to permit the passage ofthe thread from the center of the cylinder to the outer side of thelatch-guard or shield on its way to the needles, said thread in itspassage from the thread-guiding device e to the needles runnin r throughsome suitable guide, as e, the sair guide in this present instance of myinvention being re resented as a funnel or chute, and the delivery endthereoi is shown in Fig. 2 and Fig. 20. Locatinr the threadguidingdevice a centrally wit relation to the cylinder and leading the threadout from the lower end thereof enables said cylinder to be eitherrotated continuously or to be reciprocated without liability of thethread catching improperly in any stationary art of the machine, andhenoe'this central ocation of the thread-guide becomes an essentialfeature of this invention. The particular eye or device which directlydelivers the knittingthread to the machine from the shield isimmaterial, and instead of the eye or chute shown I may em loy any otherusual or suitable thread-gui ing device commonly employed inknitting-machines. In this instance of my invention the outer portion ofcylinder 6 (see Figs. 1, 2, and 5) has a flange e and above it a collare attached thereto by a suitable screw 6 and loosening said be adjustedup or down that it may be made to on said cylinder e so iTlGtlOn againstthe said act with more or less s )lit collar; but ordinarilytheadjustment of t e split collar will be all that will be rec uisite. Thecylinder, it will thus be understood, constitutes'the thread-guide-thatis, the thread is taken into the hooks from the. projecting end of theguide e, whence it passes to the needles under the adjacent edge of thecylinder e By adjusting the post e up or down in the socket e the shieldand latch-opener e may be put in exactly the proper osition withrelation to the upper ends of the needles and the size of the cone used.

The socketed arm 6 andthe thread-guide may be turned up when it isdesired to employ a transferer to put a top or other device on the hooksof the needles, they being then arranged in a circle; but when knittingis being done the said arm and thread-guide will oocu y the ositionshown inFigs. 2 and 5.

he cylinder 6 has attached to it arms a and e? b suitable like screws e"passin through s ots made in the curved shanks o the arms e 6 both shownin Figs. 1 and 2,

. most position.

said arms being preferably made adjustable toward and from the pointwhere the thread is delivered to the needles, to thereby secure accuratemovements for the threaduide With relation to the needles used. In t einstance of my invention shown in Figs. 1 and 2 the said arms arelocated in different horizontal lanes, and when circular knittin isbeing dbne, the thread-carrier being t ien rotated continuousl the arm6" is acted upon continuously y the end of a suitable lever e pivoted ate on a stand a, erected on the cam-lock a, a lug 6 at the outer curvedend of said lever at such time assing freely between the acting faces.of t e toecams d" and d", they occupying their upper- One side of thelever e is shown as acted upon by a friction device c composed, asherein shown, of a spring-steel arm erected on the stand c, it havin anattached friction-face, which may be of leather, said face beingrepresented by dotted lines behind said lever in Fig. 2, said arm alsohaving two stops e e to limit the extent of movement of said lever. r

The bed-plate has fitted within it two rings f and 9, adapted to slidetherein, the latter ring 9 resting on a shoulder g, forming part of thesaid bed-plate, and the ring f rests on the ring 9, both rings 1 ingwithin and being guided externally by t e upturned wall 9 of saidbed-plate, the upper ring f being artially overlapped by a flanged ringf he ring f has attached to it at its upper side by suitable screws 2(see Figs. 1 and 12) a steel plate, a portion 3 thereof being bentupwardly above the late and the ring f and the said upwardlyent plate issplit, so that its ends may be bent, as at 4 5, to constitute cams.suitable screws 2 (see Figs. 1 and 11) a suitalgle steel plate 3 havingcam-shaped ends 4 5 During circular knitting the rin s and remain atrest, and the cams 4 5 an 4 5 are at their farthest distances apart, andthe lever e rests against the lower stop a", and the end of said leverlies in contact with the arm 6 as shown in Fig. 2, and the threadcarrieris rotated in unison with the camring. Now when reciprocating knittingis to be commenced the cams (Z and d are automatically depressed by orthrough the pattern-surface, as described, causing the upper cam d tomeet the lug e, which slightly depresses the outer end of the lever 2",thus putting it in such position that said lever inits movement with thecam-ring will meet the end 5 of the plate 3 of ring f, which will turnsaid lever e far enough to raise its inner end from contact with the arm6 thus immediately leaving the thread-carrier at rest, so that it willno longer travel in unison with the cam-ring, the latter continuin andcompleting its usual movement, this isengagement The lower ring 9 hasattached to it by I of the lever and arm being made just after eachreciprocating course 111 either direction. This ma be done through thetwo plates 3 and 3 aving the cams described and carried by the two ringsf and g, said rings just when or after reciprocating knitting is to bedone being started by means to be hereinafter described, and movedintermittingly with respect to each other after the completion of eachstroke during narrowing, and when the narrowing has been completed thesaid rings are moved intermittingly in the opposite direction to thusagain separate said springplates ard their cams so that they operate thelever e at a later period in the stroke of the cam-ring until thewidening has been completed and circular knitting is to be againcommenced, at which time are put into their uppermost position, and onthis movement of the said cams the lever e is again put against sto e Ithas been stated t at the thread-carrier during reciprocating knittingwill be moved for a greater or less distance according to the length ofthe reciprocating course being knitted, such movement bein effectedthrough the lever e but in order t at said lever shall so operate itmust contact when the camring goes in one direction with, say, the arme, and in the opposite direction with the arm c and-the time that thesaid lever-engages one or the other ofthe said arms must beautomatically controlled. This is effected by or through the camlates 3and 3 Let it be assume that the last course of circular knitting isbeing made and that the cam-ring B is atthat time moving in thedirection of the arrow 10, (see Fig. 1,) and at this time, it will beremembered, the cams d and li are automatically lowered reparatory toreciprocating knltting, so t at cam what the outer end of the said levere and lifts the inner end thereof somewhat with relation to the arm ewith which it is in engagement. Now in the further rotation of thecam-ring in the direction of the arrow 10, Fig. 1, the lower end of saidlever strikes the incline 5, which immediately further turns the saidlever, lifting its inner end above the path of the arm e so that as thecam-ring continues its motion the said lever e elevated from contactwith the arm 6, will leave the thread-carrier at rest. The cam- Thisthreadthread-guide will be stopped at the end of the cams d d Ice IIO

d meets the lug e, which depresses somering continues its motion to thefull and of its stroke and is then reversed, and as it comes back theelevated inner end of the lever e" meets the end of the arm e, locatedin a higher plane than the arm e and immediately picks u and moves thethread-earner in unison with it; but when said thread-carrier has beenmoved so as to feed the thread to the desired number of needles to beused in that reciprmzating course the outer end of the lever c strikesthe cam incline 5 on the outer side, which l fts the outer end of saidlever, moving its inner end downwardly away from the arm 0, and thecam-rin continues its movement to the end of its stro e, leaving thethread-carrier at rest. On the return stroke of the cam-ring thedepressed inner end of the lever 14'' in line with the arm e meets saidarm and picks up and moves the thrmtd-carrier with it until the outerend of the lever c again meets the inner side of the incline 5, when theinner end of said lever-e is again lifted to pass above over and awayfrom the arm c.

The spring-plates 3 and 3 have been described as provided with. inclinesor cams 4 and 4 but these inclines or cams do not in the operation ofthemachine perform any work; but they are offset, as shown, in order thatthe outer end of the lever a, after the same has been moved by one ofthe inclines 5 or 5"", may on the return movement of the cam-ring andlever act to position the end of the lever correctly with relation tothe central part 3 or 3* of the spring-plates should the said lever fromany reason either due to centrifugal force or shock be turned somewhaton its pivot e accidentally.

The arms 0 and a are located close to the thread-delivery, one at oneand the other at the opposite side thereof, and by adjusting these armstoward or from the line of threaddelivery the thread may be led to theneedlcs of any cone correctly to enable any desired needle to be thefirst one fed for reciprocating knitting.

i believe myself to be the first to provide thecam-lock or cam-ring of acircular-knitting machine with a lever or other moving devicesubstantially such as herein described under the control of suitablecams, lugs, or projections by which said lever device may. m moved intoone and then into another position to engage and disengage at desiredtimes an arm or projection extended from or connected with athread-carrier, so that said thread-carrier may be, as it were, detachedfrom and left by the moving cam-ring at any desired point in its stroke,and therefore this invention is not limited to the exact lever or device(1 herein shown; but said lever or device may be variously modified-as,for instance, see Fig. 15, where is shown a lever h, pivoted at h on astand h which may be erected on the cam-lock-and this lever maycooperate with one arm-for instance, arm eextended from thethreadcarrier, it meeting first one and then the other side of said arm,said arm e in such modification being located immediately above saidthread-delivery. The lever has,

at one end a slot, as h, in which may be placed a roller or other studit, connected with a link or foot h pivoted at It on a block h", free toslide up and down in a slot h of an arm h of said stand it". The lowerend h of the link or foot is normally ke t depressed below the lower endof the arm by a suitable spring it, connected in this instance with astud h, fixed to the stand and to a screw or stud fixed to the lever h.The

upper end of the link 71. has a projection h provided with a hole whichembraces the end of a rod it, connected with the lever h and surroundedby a suitable spiral spring h, the said spring acting normally to keethe said link in upright position. This lin may be acted upon atsuitable times by the inclined ends it of cam-lugs h", which may befixed to two rings having circular moyement. as described, of the ringsf and g, and said rings may be either constructed as shown in thisapplication or said cam-lugs may be applied to a ring which has impartedto it not only a circular motion, but a rising-and-i'alling motion, asin United States Patent No. 542,055, dated July 2, 1895. The upwardmovement of the leg h" by one of the said cam ends depresses the innerends of thelever h to remove it from contact with one side of the singlearm extended from the threadcarrier with which it cooperates, and assoon as the leg passes off of the end of the said cam the spring himmediatelyacts to elevate the inner end of the lever it, again puttingit in the path of the arm extended from the thread-carrier, and thecam-ring continues its movement to the end of its stroke. On the returnstroke the end of the lever it must meet the opposite side of thearmextended from the thread-carrier in order to move the thread-carrierin the opposite direction, and in order that the end of the lever mayremain in its elevated position and not be depressed by the cam referredto the inner edge h of the leg it meets an inclined portion h of saidcam, which turns the leg on the pivot h, so that the saidleg is notlifted, as it was when it passed the cam in its stroke in the otherdirection, and consequently the rollerstud it moves in the slot h andthe inner end of the lever is not at all disturbed, but remains incontact with the arm extended from the thread-carrier and moves thethreadcarrier until the lower end of the leg h meets a second like camend h on the other ring,by

- which it is elevated, as just described, so that the inner end of thelever h is depressed below and passes beyond the arm extended from thethread-guide, thus again leaving the thread guide at rest, and thiseration will be repeated at each stroke of t e cam-ring duringreciprocating knitting.

The cam-lock 01 (shown best in Figs. 6 and 7 and in the section Fig. 8)has two stitchregulating cams m m, two being used because the machine isto knit on the reciprocating stroke. Thesecams are carried by suitableslide-blocks m. The carriage m, carrying the cam m, has a stud m whichis extended outwardly through a slot m In the cam-lock a, said lockhaving ad'ustabl secured to it a late m whichis seti or the ongeststitch to e made in heel and toe work, and the cam m is adjusted tonormally stand in the same position by or through the lowest projectionof the pattern-surface; but when a longer stitch is to be made incircular work,

' as toward the upper end of the leg, said cam m is depressed by orthrough a projection on the pattern-surface acting upon a ring m, (shownin section in Fig. 5 and in elevation in Fig. 1,) said ring havingsuitable ins or studs m extended from it through t e bed-plate Aunderneath the rings f and g, the ends of said pins or projectionsentering suitable slots m (see Fig. 2) in a series of adjustable lates mfixed on the bed-plate A. To li t this ring and render it available tolengthen the stitch, as described, it must be turned, and to a do this Ihave provided the ring with an arm right-an led stud n, w

m", (see Figs. 1 and 2,) which is extended through a suitable hole inthe outer u right wall of the bed-plate, where it is acts upon by a hookm carried by a stud m on an elbow-lever m havin one of its arms extendedover and so as to is acted upon b a projection of the attern-chain, thesai projection turning t e said lever m so that the hook m, acting onthe rod m, draws the said rod in a circular path, causing theprojections m to slide upwardly in the inclined slots m, thus raisingthe ring. The upper side of the ring as it is raised contacts with afoot m" of a slide or lever m, suitably pivoted at the outer end of thecam-lock a", said lever having jointed to it a link a, which engages oneend of a lever m pivoted atm, the opposite end of said lever having anadjusting-screw m", which acts upon the stud m extended outwardly fromthe slide m carrying the said cam m. The cam-lock also has two likefly-cams n each of which has a wardly t ough a hole in the cam-lockwhere said stud is surrounded by a suitable sprin n, one end of said sring being connects with the cam-lock an the other with a suitable pinor projection n, extended throu h or connected with said stud, so thatsaid spring normally acts to keep the fly-cam pressed against the blocks62 and 63.

The plate of the cam-lock has attached to its inner side, as hereinshown, by suitable screws a series of blocks 60, 61, 62, and 63, the

blocks 60 being in duplicate,

ch is extended out,

and they are so shaped at their under sides and so located wit relationto the blocks 61, 62, and 63 as to leavebetween them what I designate asthe knitting-groove n, the said knittinggroove intersecting the loweredge of the cams m and m before described. The outermost ends of theblocks 60-have ivoted on them the fly-cams n described, and to the innerends of said blocks are pivoted the points or switches n n. The centralpart of the block 61 is provided with a recess to receive a block 64, itbeing attached to the block'61 b3 a screw 65. Above the concaved upper egeof the block64 ispivotedadirecting-cam 66, said cam occupying aposition between said points or switches n n, the directingcamdependincg in a space between the lower a gui e edges 0 -plate 67.

he top edges of the blocks 60, 62, and 63 and the fly-cams n and the topof the block 64 and the up or edge of the ring a, constitute one side oiwhat is designated as the nonknitting groove u the only opposed side being the small ui'de-plate 67 and the directing-cam. In t e patentsreferred to the nonknitting groove had a continuous top wall extendedentirely about the cam ring; but for cheapness of construction and tolessen thedwear on the butts of the needles when in sai the butts of theneedles in said groove free to be seen I have done away'with most of theupper wall of said non-knittin groove.

he fly-cams normally stan in position to close the knitting-groove andprevent the entrance ofneedles therein at that point but they are freeto rise and permit the passage of the butts of the needles from theknitting-groove into the non-knittin groove n.

Substantially mi wa cams m and m I have ocated the needle-selectingdevices, composed, essentially, of the two points or switches n n,represented as pointing one toward the other, and a directing-cam 66,loosely pivoted and lyil'ig between the s'aid points or switches, saiddirecting-cam being free to be struck by the butts of the needles whenthe cam-ring is moving in either direction, so that it if the free endsof the said points or switches are elevated will insure the passage ofthe butts of the needles under the points or switches into theknitting-groove 11,; but if the free ends of said points or switches aredepressed then the butts'oi the needles on arriving under the betweenthe stitchdirecting-cam pass beyond it over the tops of the free ends ofthe points-or switches and remain in the non-knitting groove and do notknit. In Fi 17 I have shown oneof these points or switches detached, andit will be seen that it has extended from its back a stud n. The studsextended from these points or switches enter each a hole in a slidingplate n", entering a suitable groove in the 95 non-knitting groove andto also leave passes throu h a cam-slot a, made in an arm n, extendefrom what I herein designate as a toe-cam N, said toe-cam having twotoes n" 71., extended from a hub n in opposite directions and indifferent planes. The hub of the toe-cam has a hole a", which is passedover a stud a, rising from the cam-lock.

The arm n of the toe-cam rests at its under side upon a rock-shaft n", aportion of which is slabbed off or cut away at 11. (see Fig. 8) to leavea secant surface. This rock-shaft has connected to or forming part of ita ear a, which is engagedby a segmental rack n at one end of a lever npivoted at n on a stand a, erected on the cam-lock, the outer orleft-hand end of said lever, viewing Figs. 2 and 8, being so located asto pass between the two cams d d when the said cams are in their upermost position and circular knitting is eing done; but whenreciprocating knitting is to be done and the said earns (1 cl aredepressed, as stated, the up ermost cam d meets the upper side of theever a and depresses that end, turning the rockshaft until the secantsurface a comes immediately under the arm a, thus letting the toecamdrop and put'the toes n" n in position to strike a ainst the devices,which at each stroke of t e cam-ring in reciprocatin knitting act toturn the said toe-cam to t ereby cause its slotted portion a to act atthe proper time through the stud n to thereby move the piate n to eitherelevate the saidpoints or switches to pull down the needles from thenon-knitting groove into the knittingroove for knitting either incontinuous I circu ar courses or for reciprocating courses, as innarrowing and widening, or to depress said points or switches to retainthe butts ofsaid needles in the non-knitting groove. 1 have previouslydescribed in the preamble of this s ecification the action of thesepoints or switc es in their elevated and depressed potions, and theiraction is as common in the patents previously referred to so need not beerein furtherdescribed; but I will now describe how the toes of thetoe-cam are acted upon and moved at the proper times.

, Referrin now to Figs. 1, 5, 11, and 12, the

- rings f an g before referred to are therein has secured to itrepresented, and the ring b suite le rackb suitable screws 0 an p ates 0each having suitable depending lugs,

as 0 0, the contiguous ends of said lugs being oppositely beveled, asbest represented in Fig. 12, and it will also be noticed in Fig. 1 thatthe said lugs stand in different circles, and in 1 Fig. 12 they stand atdifferent levels viewed from a horizontal glane. Supposing, a ain, thatthe cam-ring is moving in the weetion of the arrow 10, Fig. 1, in itslast course of circular knitting preparatory to being reversed forreciprocating knitting and that the cams d d have been depressed to putthe toe-cam down, as described, with its toes n n in working position.During the last partof the last circular course the under side of thetoe it meets the bevelede'nd of the lip 0 and the toe-cam is turned todepress 'the points or switches a a between the two needles, asdescribed, so that thereafter no'more needles will enter theknitting-groove a, but

will follow over the tops of the point or switch just turned under itinto the nonknitting groove, and by the time that the last needlepassesthefl -cam n and enters the non-knitting groove t 1e first needle topass over the point will be found in position alongside 'the'last needleand the butts of all the needles will be in the non-knitting groove. Nowthe machine is in condition to be reversed, and as soon as the points orswitches in the first reciprocating stroke of the machine opposite thearrow arrives in a position to have a point or switch elevated betweentwo needles to thus }grab and pull down i into the knitting-groove t efirst of the series of needles to be used for a narrowing or wideningcourse the shoulder of the toe it" meets the inclined end of the lug 0whichimmediately turns the toe-cam in the direction of the arrow nearthe toe a" in Fig. 9 and again lifts the points or switches intoposition to engage and depress the first needle to be used in thatreciprocating course, and the points or switches remain up until all ofthe needles to be used in that reciprocating course have been taken fromthe non-knitting groove and put into the knitting-groove to knit, andwhen the last needle of said course has completed its operation the toen of the toe-cam meets the beveled end of a lug 0 fast on the ring g,said lug again turning the toe-cam, causing the points to be depressedbetween two needles, and thereafter the butts of the needles in thenon-knitting groove pass over the points or switches, while the butts ofthe needles then in the knittingroove pass out of said knitting-grooveinto t e non-knitting groove in front of the needles traveling in thenon-knitting grooves until the butts of all the needles are again inmass in the non-knitting groove. The cam-ring completes its reciprocating course and comes back, and as soon as it arrives op ositc theneedle to be a ain depressed for tile first needle of that reciprocatingcourse a like cam projection of the toe n" meets the beveled end of alip 0 extended upwardly from the ring g, which again turns the toe-camto elevate the points or switches so that the needle to be the firstv ofthat course is immediately drawn down into the-knittinggroove.

The lugs 0 and 0 are directed, res ecmotion to thereby The plates 0carrying the lugs 0 ojiand the plates carrying the lugso 0 may beadjustfirst needle of a reciprocating course and also to enable a pointor switch to pass between the butts of any two needles, one of saidneedles being the last one to be used in the reciprocating course. Itwill be understood that the lugs 0 0 on one side of the machine I 5 Jand the lugs 0 0 on the other side of the machine stand at theirfarthest distances apart when reciprocating knitting is commenced andthat at the end of each stroke of reciproeating knitting the said pairof cams are :0 moved intermittingly one toward the other until thenarrowest course of reciprocating 'knitting is being made, and then theywill be gradually moved intermittingly in the opposite direction backfor widening into their 2 5 starting position. I will state, however,that these rings are not in this particular machine moved at the firsttwo strokes of reciprocating knitting, I not moving them, because I havefound'that by laying in two courses of reciprocating knitting beforecommencing to narrow it is possible to make a better junction of thenarrowed part with the circular part thanwould be the case if the ringscarry- 1ng the lugs were moved with the first nar- 5 rowing course. Iwill now describe how these rings f and g are moved intermittingly inopposite directions. I have devised a very simple means for thispurpose, my means containing but very few parts of light weight,

0' low cost, and easily actuated. Each of these rings is provided withteeth at its peripher the said teeth extending substantially halfwayaround each ring, and the toothed parts of these rings extend through aslot in the up- 5 per vertical wall 9 of the bed-plate, as seen Theupier ring.

at the right in Figs. 1 and 5. f is engaged by a pinion 34, connectewith a sleeve 36, having at its lower end a pinion 37, said two pinionsand sleeve being loose on a shaft 35, held in a suitable'bearing 38,connected with the bed-plate. The bed-plate has another. suitablebearing 39, in which is mounted a shaft. 40, (see Fig. 1,) provided atits upper end with a toothed pinion 41, the

pinion being of sufficient thickness from top to bottom to not onlyengage the teeth of the ring g, but alsoto engage the teeth of thepinion 37 referred to, so that in the rotation of the pinion 41 it actsto move the ring gin one 6o direction and, acting through the pinions 37and 34, causes the pinion 34 to move the rin f in the oppositedirection, each being move at exactly the same time in op ositedirections without any ossibility o slip or lost d isarrange therelative positions of the cam-lips and devices carried by said rings.The lower end of the shaft 40 has attached to it a pinion forratchet-wheel a,

(see Figs. 2 and 3,) and/said ratchet-wheel is pawl-carrier once duringeach rotation of said shaft. Each pawl c and c has a like tee a, whichbutts against a projection of the ear 0 and is kept there in a yieldingmanner by a suitable spring 0, the toe c limiting'the inward movement ofthe pawls c and c.

To provide for the pawls c and 0 contacting with the ratchet-wheel c" tomove the shaft 40, I have provided a lever 44, pivoted at 45. One end ofsaid lever has jointed to it a link 46, connected to the lower end of anelbow-lever 47, pivoted on a stud held in a boss 48 (see Fig. 2) of theframework, the short horizontal. arm of said elbow-lever being slotted,(see Fig. 19, where said lever is shown in detail,) the said slotreceiving a pin 49, extended laterally from the elbow-lever d, beforedescribed, so that when said lever is elevated or moved by thepattern-surface the lever 47 is consequently moved. The front end of thelever 44 referred to has con-v nected'to it a link 50, which embracesloosely a stud 51, carried by a plate 52, pivoted on a stud 53, erectedon a plate 54, fast to or forming part of the standardA (See Fig. 2.)

The pawl-carrier C, before described, in its forward'and backreciprocation is guided by the plate 52, before described, and theforked end of the carrier slides back and forth on or about the stud 51,and when it is desired to place one or the other of the pawls c or c inengagement with the ratchet-wheel c the lever 44 must be moved.

Now assuming that it is desired to place the pawl c in engagement withthe ratchetwheel 0 then in such case the pattern-surface willautomatically at the proper times move the inner or short arm of thelever 44 to the left, viewing Fig. 3, and will carry the plate 52 andthe pawl-carrier laterally, thus putting. the pawl c in engagement withthe teeth ofthe ratchet-wheel, and said pawl will remain in engagementwith said teeth and in the reciprocations of the pawl-carrier will movesaid teeth and the shaft 40 as long as the rings are to be moved in thedirection for narrowing, and, the narrowing completed, the lever 44 willbe again moved in a direction to insure the placing of the 1pawl c inposition to engage the ratchet-w eel c and turn IIO lo 824,,d08
